Provided is an adjustable optical assembly (900), including a bearing base (921), a driving mechanism (910), a zoom optical assembly (200), and a compensating optical assembly (300). The driving mechanism (910) includes: a bracket (911) having a bottom end connected to the bearing base (921) and a top end having a top groove (911a) open upwards; guide rods (912, 913) supported on the top groove (911a), the guide rods (912, 913) coinciding with the direction of optical axes of the zoom optical assembly (200) and the compensating optical assembly (300); a zoom bearer (914); a compensating bearer (915); a zoom driving assembly; and a compensating driving assembly. The zoom bearer (914) and the compensating bearer (915) are both mounted on the guide rods (912, 913) and slidable along the guide rods (912, 913). Also provided are a corresponding periscopic optical zoom module and an assembly method therefor. According to the adjustable optical assembly (900), the bracket (911) and the guide rods (912, 913) are disposed on the bearing base (921), thereby effectively ensuring that the moving directions of a zoom group and a compensating group do not deviate from a main optical axis. Moreover, the adjustable optical assembly (900) is compact in structure and convenient to assemble, and facilitates large-scale mass production.

An optical system is provided. The optical system includes a first optical module and a second optical module. The first optical module is used for connected to a first optical element. The second optical module is used for connected to a second optical element. A light enters the first optical module along an incident direction, and the light is adjusted by the first optical module to enter the second optical module along a first direction. The incident direction is not parallel with the first direction.

Provided is a prism device applied to a periscope lens module. The prism device includes: a bearing frame; a supporting-restoring assembly; a prism; and shape memory alloy wires configured to drive the supporting-restoring assembly and the prism to rotate relative to the bearing frame. Two opposite sides of the bearing frame are each provided with limiting grooves, two opposite sides of the supporting-restoring assembly are each provided with limiting arms inserted into the limiting grooves in one-to-one correspondence; and each limiting arm and a corresponding limiting groove form a clearance fit in such a manner that the limiting arm is movable in the limiting groove. In the present invention, two opposite sides of the bearing frame are provided with limiting grooves, and limiting arms on the supporting-restoring assembly are inserted into the limiting grooves, thereby preventing the supporting-restoring assembly from escaping from the bearing frame during use.

A camera module includes an imaging lens system, an image sensor and a plurality of light-folding elements. The imaging lens system is configured to focus imaging light onto an image surface. The image sensor is disposed on the image surface. The plurality of light-folding elements includes at least one image-side light-folding element disposed on an image side of the imaging lens system, and each of the light-folding elements is configured to fold the imaging light from an entrance optical path thereof to an exit optical path thereof. At least one light-shielding mechanism is arranged on at least one of the entrance light path and the exit light path of the at least one image-side light-folding element. The at least one light-shielding mechanism has a minimal opening, and the minimal opening surrounds the imaging light in the at least one of the entrance optical path and the exit optical path.

An optical member driving mechanism is provided. The optical member driving mechanism includes a fixed portion, a movable portion, an electromagnetic driving assembly and an elastic member. The fixed portion has a base and a frame that is disposed on the base. The movable portion is movable relative to the fixed portion, and includes a carrier for carrying an optical member with an incident optical axis. The carrier includes a body and a sidewall that extends along the edge of the body, wherein the carrier further includes a first stopping portion and a second stopping portion protruding towards the fixed portion. The electromagnetic driving assembly drives the movable portion to move relative to the fixed portion. The movable portion is movably connected to the fixed portion via the elastic member.

An optical member driving mechanism is provided, including a movable portion, a fixed portion, a driving assembly, a light emitter, and a light receiver. The driving assembly is configured to drive the movable portion to move relative to the fixed portion. The light emitter emits light toward an object, and the light receiver receives the light reflected by the object.

Provided is a periscope lens module, including: a prism; a bearing member including a bearing frame; a ball; a supporting member including a prism bracket, a driving bracket, and a rotating bracket in rotation-fit with the ball; an elastic member; and a driving member. The elastic member includes a first elastic bracket including a first abutting portion, and a second elastic bracket including a second abutting portion. The first and second abutting portions are spaced from each other and abut against a top of the rotating bracket from two sides of the ball, in such a manner that the rotating bracket and the ball abut against the bearing frame. The driving member is connected between the bearing member and the driving bracket for driving the supporting member to drive the prism to rotate. This leads to a simple structure while achieving image stabilization.
